Kafo > 0.0.12 allows to specify custom log filename

So let's discuss log filename.

The project is called ```foreman-installer```, the script is named according to action ```foreman-install```, later we may add other scripts like ```foreman-check``` or whatever 

I prefer having log files in ```/var/log/$project_name/$script_name``` in this case ```/var/log/foreman-installer/foreman-install.log```

Also note that this won't have any effect until Kafo 0.0.13 is released.
